The aim of the study was to compare the content of ergosterol in different microorganisms (bacteria, yeasts and moulds) isolated from the air as well as in six species of moulds in their different morphological forms-live mycelium, dead mycelium, and spores. Evaluation of the level of mould contamination of the air in various places using culture method and ergosterol determination was also per...

Branching morphogenesis of the Drosophila tracheal system relies on the fibroblast growth factor receptor (FGFR) signaling pathway. The Drosophila FGF ligand Branchless (Bnl) and the FGFR Breathless (Btl/FGFR) are required for cell migration during the establishment of the interconnected network of tracheal tubes. However, due to an important maternal contribution of members of the FGFR pathway...

PURPOSE To develop and characterize a telomerase-immortalized human corneal epithelial cell line (hTCEpi) to serve as an in vitro model for studying the molecular mechanisms involved in regulating human corneal epithelial cell differentiation. METHODS Primary cultures of human corneal epithelial cells were infected with a retroviral vector encoding human telomerase reverse transcriptase (hTER...

a four year long research programme divided into four phases has been designed for the first time to assess the combined noise-air quality and combined exposure to noise-air pollution at the curbside open-air microenvironment of kolkata city, india. the results and the findings of the different phases of study had already been published. the objective of the review work is to fuse the findings ...

the study was undertaken to elucidatethe beneficial effects of goat follicular fluid (gff) added to maturation and culture media on in vitro maturation, fertilization and post-fertilization development of oocytes in black bengal goats. follicular fluid and oocytes were collected from slaughter house goat’s ovaries using the aspiration technique. media were prepared using tcm-199 supplemented wi...

A key component of a Solid Oxide Fuel Cell (SOFC) is the interconnect, which connects individual fuel cells in series to form cell stack reach desired electrical potential. The interconnect exposed air and parallel, these so-called dual-atmosphere conditions give rise especially severe corrosion on air-side. This work investigates coatings mitigate this effect. Physical Vapour Deposition (PVD) ...

A study of detonations in high molecular weight hydrocarbon fuels was performed in two GALCIT facilities: the 280 mm gaseous detonation tube (GDT) and a 1180 liter vessel (HYJET) with jet initiation capability. In the GDT, detonation pressure, wave speed and cell width measurements were made in hexane-oxygen-nitrogen mixtures with and without the addition of lower molecular weight fuels. Stoich...

A biocathode was designed by the modification of a carbon nanotube (CNT) gas-diffusion electrode with bilirubin oxidase from Bacillus pumilus, achieving high current densities up to 3 mA cm(-2) for the reduction of O2 from air. A membraneless air-breathing hydrogen biofuel cell was designed by combination of this cathode with a functionalized CNT-based hydrogenase anode.

Electricity is an irreplaceable part of people's lives, almost all human activities, both in households, offices, and industry. However, some areas that have not been reached by the Perusahaan Listrik Negara (PLN) , other sources electrical energy are needed one solution to use solar which can later be used for daily life, turn on water pump. Based this problem, authors made automatic control s...
